Crate fitscube_rs 

Combine single-frequency (or single-time) FITS images into a FITS cube.

A Rust port of the fitscube Python package. Also available as a Python package (fitscube_rs) and a CLI tool (fitscube).

Overview

• combine_fits: stack a list of images into a cube along the frequency or time axis (combine module), handling uneven spacing, blank-channel interpolation, per-channel beams, and bounding-box trimming.
• extract_plane_from_cube: pull one channel/timestep back out of a cube (extract module).

Assumptions (inherited from the original): all inputs share the same WCS and pixel grid, and the frequency/time of each image is available either as a WCS axis, the REFFREQ keyword, or the DATE-OBS keyword (time mode).

Per-channel restoring-beam handling.

bounding_box

Bounding-box geometry for trimming blank padding from images.

combine
